A generic point on the graph of the curve has coordinates

The derivative gives us the slope of the tangent line at a given point:

Let k be a generic x-coordinate. The tangent line to the curve at this point will pass through
and have slope 
So, we can write its equation using the point-slope formula: a line with slope m passing through
has equation

In this case,
and
, so the equation becomes

We can rewrite the equation as follows:

We know that this function must give 0 when evaluated at x=0:

This equation has no real solution, so the problem looks impossible.
Answer:
0
Step-by-step explanation:
To find the slope, we use the formula
m= (y2-y1)/(x2-x1)
= (6-6)/(-2-4)
= 0/-6
=0
Answer:
The probability density function for the average length of life of the two components is 
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following probability density:

In which
is the decay parameter.
Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.
2, each with mean 1 means that 
So the probability density function is:

Well if hes gonna add .25 cents every 6th month then i think you would have to pick D because it shows the starting pay (5.50) then adds the .25 for every 6th month. Hope i helped :)
